Every year, when February arrives, searches for ‘affordable heating’ skyrocket. And, of course, this is no coincidence. This month usually brings together freezing temperatures and consumption peaks. This results in bills that reflect the extra effort households make to maintain thermal comfort during the final stretch of winter.

Why February is one of the most expensive months for heating

Late-season cold snaps increase consumption

February often brings episodes of intense cold, sometimes even harsher than in December or January. With the cold fronts currently hitting the Spanish peninsula, heating systems are being forced to run for longer hours and at higher output. This increases energy consumption and, consequently, monthly bill costs.

Poorly insulated homes face higher expenses

Homes with old windows, thermal bridges or poorly insulated walls lose heat quickly. In February, when the temperature gap between indoors and outdoors is still significant, these losses become more pronounced. As a result, heating must run longer to maintain a stable temperature.

Increased use of domestic hot water (DHW) in late winter

Domestic hot water also affects your bill. During colder months, the incoming water temperature is lower, forcing boilers and water heaters to work harder to reach the desired temperature. This increases energy consumption even if daily usage remains the same.

Which heating systems become more expensive in February

Natural gas

Natural gas is usually stable. However, consumption rises in February due to higher demand for heating and hot water. Old or inefficient boilers can significantly increase costs, especially in large or poorly insulated homes.

Electricity

Electric systems such as radiators, storage heaters or heat pumps can become more expensive if used during peak hours or in poorly insulated homes. Still, modern inverter-based equipment maintains strong performance even at low temperatures.

Butane and propane gas

Fuels such as butane and propane usually become more expensive in winter due to increased demand. In February, cylinders are used up more quickly due to intensive heating use. This leads to more frequent replacements and often pushes monthly expenses higher than expected.

Biomass and pellets

Although biomass is an affordable option, February often coincides with higher pellet prices due to strong demand. Daily consumption also increases, especially in stoves that run for many hours in a row.

Which heating system is truly the most cost-effective in February?

Heat pump (aerothermal systems)

Aerothermal systems are among the most efficient on the market. Even in winter, they can deliver three to four times more energy than the electricity they consume. In February, when usage is intensive, this efficiency translates into significant savings.

Natural gas (depending on boiler and usage)

With a modern condensing boiler and responsible use, natural gas can be a competitive option. Its cost depends on home insulation and the selected temperature.

Pellet stoves

Despite the seasonal rise in pellet prices, they remain an affordable alternative for well-insulated homes or large spaces where steady heat is needed.

Electric radiators

Electric radiators can be economical when combined with time-of-use tariffs and smart usage. They are especially useful in small or well-insulated homes.

How to save on heating in February without changing systems

The extra-degree trick

Lowering the thermostat by just one degree can result in energy savings of 6% to 7%. Keeping your home between 19°C–21°C is sufficient for most households.

Optimise heating schedules

Programming your heating to operate only when needed prevents unnecessary consumption. In February, when nights are cold, adjusting schedules helps avoid overuse.

Quick insulation solutions

Simple measures such as draught excluders, thermal curtains or rugs help retain heat. These low-cost solutions immediately reduce energy loss.

Bleed radiators

In hot water systems, bleeding radiators improves efficiency and ensures proper heat distribution. It’s a quick task that can lower consumption.

Close unused rooms

Focusing heat only on the rooms you actually use is a simple way to prevent wasting energy. In February, this strategy can make a noticeable difference on your bill.

The best electricity and gas tariffs for February: How to choose and pay less

For electricity, time-of-use tariffs are often highly beneficial if you can shift your most intensive energy consumption to off-peak hours.

Meanwhile, for natural gas, fixed-rate tariffs help avoid surprises during the coldest months. Comparing prices, reviewing conditions and adjusting your contracted power can lead to significant savings in February, when energy consumption reaches one of its annual peaks.

If you’re looking for a hassle-free, efficient option, the Conecta tariff by Endesa provides a stable electricity rate with no long-term commitment and a competitive price 24/7. It’s perfect for households that want to control spending without relying on schedules. This stability makes it easier to predict bills in colder months while maintaining comfort without sacrificing savings.
